Having Problems Locating a House Owner

[Shelby Lynn Colter]

Hello, 

I am having problems locating the owner of a abandoned duplex. It appears that the property has gone through foreclosure and has been put in many sheriff sales. However, it is unclear who is still in possession of the property. There is no real estate agent to ask either and no phone numbers or emails. Does anyone have any advice on moving forward? Any help is greatly appreciated!
